Following code used in fragment : -

new ChooserDialog().with(getActivity())
                .withFilter(false, false, "jpg", "jpeg", "png")
                .withResources(R.string.dtp_file, R.string.title_choose, R.string.dialog_cancel)
                .withChosenListener(new ChooserDialog.Result() {
                    @Override
                    public void onChoosePath(String path, File pathFile) {

                        }
                    }
                })
                .build()
                .show();

add .withStartFile(startingDir)

Experiencing the same here. Log is;

java.lang.NullPointerException: Attempt to invoke virtual method 'java.io.File[] java.io.File.listFiles(java.io.FileFilter)' on a null object reference at com.obsez.android.lib.filechooser.ChooserDialog.listDirs(ChooserDialog.java:288) at com.obsez.android.lib.filechooser.ChooserDialog.refreshDirs(ChooserDialog.java:371) at com.obsez.android.lib.filechooser.ChooserDialog.build(ChooserDialog.java:204)

My code is:

 btnUpload.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                new ChooserDialog().with(getActivity())
                        .withStartFile("")
                       // .withStartFile(Environment.getExternalStorageState()+"/")
                        .withFilterRegex(false, false, ".*\\.(jpe?g|png)")
                        .withChosenListener(new ChooserDialog.Result() {
                            @Override
                            public void onChoosePath(String path, File pathFile) {
                                Toast.makeText(getContext(), "FILE: " + path, Toast.LENGTH_SHORT).show();
                            }
                        })
                        .build()
                        .show();
.............................

Kindly assist. EDIT: It failed even with .withStartFile(Environment.getExternalStorageState()+"/")

[hedzr]

it seems that caused by _currentDir is null, in ChooserDialog.java#L312: File[] files = _currentDir.listFiles(_fileFilter);, with an earlier version used. so:

• try the newest version 1.1.9
• withStartFile(null), or .withStartFile(Environment.getExternalStorageDirectory().getAbsolutePath()),
• make sure permissions XX_WRITE_EXTERNAL_STORAGE
• post a sample repo link that can reproduce the errors and let me have a try.
• or debug deep into the source codes.

just checked: withStartFile("") cause _currentDir == null. as a workaround, replace it with withStartFile(null) or .withStartFile(Environment.getExternalStorageDirectory().getAbsolutePath()).
